DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0029] like Figures 1 to 7As shown, a stainless steel plate filter screen in one embodiment of the present invention includes a first filter plate 1 having multiple sets of first filter ports 101 formed thereon. A second filter plate 2 is movably connected to the first filter plate 1, and the second filter plate 2 has multiple sets of second filter ports 201 that match the first filter ports 101. Under normal conditions, the first and second filter ports 101 are aligned with each other, allowing sewage to flow outward therethrough and filter the sewage. The first and second filter ports 101, 201 are both rectangular. When the second filter plate 2 is moved, the second filter ports 201 become misaligned with the first filter ports 101. Thus, the size of the first filter ports 101 can be adjusted by moving the second filter plate 2.

[0030] like Figure 3 As shown, multiple groups of filter holes 3 are provided on the second filter plate 2. When the second filter plate 2 is moved, the filter holes 3 can also be aligned with the first filter ports 101. At this time, all the first filter ports 101 on the first filter plate 1 will be blocked by the second filter plate 2, and only the filter holes 3 can allow the sewage to leak out. In this way, the filter holes 3 are used instead of the first filter ports 101 to meet different usage requirements.

[0031] like Figure 5 As shown, a groove 106 is defined in the first filter plate 1, and the second filter plate 2 is slidably connected within the groove 106. The space within the groove 106 is larger than the second filter plate 2, and the opening at the bottom is smaller than the second filter plate 2. This allows the second filter plate 2 to move freely within the groove 106 without falling out. A protective gasket 4 is fixedly connected to the interior of the groove 106. The protective gasket 4 protects the second filter plate 2 within the groove 106, preventing wear caused by contact between the two plates.

[0032] like Figure 6 and Figure 7 As shown, multiple sets of first limiting ridges 105 are fixedly connected to the interior of the groove 106, and multiple sets of second limiting ridges 205 that match the first limiting ridges 105 are fixedly connected to the second filter plate 2. The first limiting ridges 105 and the second limiting ridges 205 are both made of elastic material. When the second filter plate 2 is moved, the first limiting ridges 105 and the second limiting ridges 205 can contact each other and deform when squeezed. After moving it to the other side, it can fix the second filter plate 2, thereby ensuring its stable installation.

[0033] like Figure 5 、 Figure 6 and Figure 7As shown, the interior of each set of first filter ports 101 is fixedly connected to a first scraper 102 that matches the second filter ports 201. The first scraper 102 is slidably connected to the interior of the second filter ports 201 and is in close contact with the sidewalls of the second filter ports 201. The interior of each set of second filter ports 201 is fixedly connected to a second scraper 202 that matches the first filter ports 101. The second scraper 202 is slidably connected to the interior of the first filter ports 101 and is in close contact with the sidewalls of the first filter ports 101. When the second filter plate 2 is moved, the first scraper 102 and the second scraper 202 can be used to scrape and clean the interiors of the first filter ports 101 and the second filter ports 201, respectively, to remove dirt accumulated in the first filter ports 101 and the second filter ports 201, ensuring their internal cleanliness and preventing clogging of the filter screens.

[0034] The first end of the first scraper 102 that passes through the second filter opening 201 is fixedly connected to the first limiting plate 103, and the first limiting plate 103 is attached to the second filter plate 2. The second end of the second scraper 202 that passes through the first filter opening 101 is fixedly connected to the second limiting plate 203, and the second limiting plate 203 is attached to the first filter plate 1. The first limiting plate 103 and the second limiting plate 203 can limit the first filter plate 1 and the second filter plate 2, so that they can fit together more tightly and improve their service life.

[0035] like Figure 4 As shown, the first filter plate 1 is provided with multiple groups of first openings 104 that match the second scraper 202, and the second filter plate 2 is provided with multiple groups of second openings 204 that match the first scraper 102. The second filter plate 2 can be moved longitudinally through the first openings 104 and the second openings 204 to avoid interference from the first scraper 102 and the second scraper 202. In this way, the second filter plate 2 can be used to completely block the first filter openings 101 on the first filter plate 1, so that the filter screen becomes a baffle, which plays the role of cutting off the water flow.

[0036] like Figure 1 As shown, multiple groups of mounting holes 5 are provided on the first filter plate 1, and multiple groups of anti-slip sheets 6 are fixedly connected to the second filter plate 2. The provided mounting holes 5 can facilitate the installation of the filter screen, and the anti-slip sheets 6 can increase the friction on the second filter plate 2 to facilitate its movement.

[0037] During specific use, the filter can be installed in the use position. During use, the aperture of the first filter port 101 can be adjusted by moving the second filter plate 2. During the movement, the first and second scrapers 102 and 202 can also be used to clean the first and second filter ports 101 and 201 to remove accumulated dirt. In addition, the filter holes 3 can be aligned with the first filter port 101, so that the filter holes 3 replace the first filter port 101 to meet different filtering needs. Furthermore, the second filter plate 2 can be used to completely block the first filter port 101 on the first filter plate 1, thereby cutting off the water flow.

[0038] The utility model provides a stainless steel plate filter screen, which is installed in a movable connection manner by providing a first filter plate and a second filter plate, so that the second filter plate can move on the first filter plate. During the movement, the second filter plate can be used to block the first filter port, thereby adjusting the aperture thereof to meet different usage requirements. By utilizing the coordinated arrangement of the first scraper and the second scraper, the first filter port and the second filter port can be cleaned during the movement to remove dirt inside the first filter port, thereby ensuring the usage state of the filter screen.
